MECHANICAL OILER FOR SHAFTNG.

SPECIFICATION forming part of Letters Patent No. 515,749, dated March 6, 1894.

Application filed January 25,1893- Serial No. 459,654- (No model.)

To all whom t may concern:

Be it known that I, GEORGE H. COLE, acitizen of the United States, residing atLowell, in the county of Middlesex and Commonwealth of Massachusetts, have invented a certain new and useful Improvement in Mechanical Oilers for Shaftin g, of which the following is a specification. 4

My invention relates to mechanical oilers for shat'ting, and consists in the devices and combinations hereinafter described and claimed, whereby oil is raised from a reservoir, with which the journal-box is provided, to the shaft, and is thence removed to channels which convey said oil along the entire length of the bearing surface of the shaft.

In the accompanying drawings on two sheets, Figure 1 is a vertical longitudinal section on the line 1 1 in Fig. 2, of a journal-box having my improved devices for oilin g ashatt, showing in front elevation a piece of shafting supported in said journal-box; Fig. 2, a vertical cross-section on the line 2 2 in Fig. 1; Fig. 3, like Fig. l, except that the shaft, oilraising roll and its supporting springs are omitted and a part of the anti-friction lining of the upper half of the box is broken away 5 Fig. 4, a plan of the lower half of the journal-box; Fig. 5, avertical longitudinal section on the line 5 5 in Fig. a, of apart of the lower half of the journal-box, showing a receivingchannel and the adjacent parts of a distributing channel; Fig. 6, a vertical cross-section 'of the journal-box, on the line G 6 in Fig. 1, omitting the shaft;` Fig. 7, a vertical lcrosssection on the line 7 7 in Fig. 3, omitting the shaft; Fig. 8, a plan of a part of the journalbox at the reservoir end, with a piece of shafting contained therein, a part of the upper half of the journal-box being removed to show the wiper; Figs. 9 and 10, showing a ring looselysurrounding the shaft and supported thereon and dipping into the oil, said ring beinga substitute for the oil-raising roll, shown in Figs. 1, 2 and 7; Fig. 9 being a vertical cross-section on' the line 9 9 in Fig. 10, and Fig. 10 being substantially like Fig. 8, except that, the ring being substituted for the roll, the reservoir part of the journal-box is a part of the cap or upper member of the journal-box, showing the deiector and the hole in said cap which receives said deliector; Fig. 12, a vertical section on the line 12 12 in Fig. 11 of the journal-box and shaft, showing a side elevation of the deiiector and its cover; Fig. 13, a vertical cross-section of a part of the journal-box and shaft, showing a slightly modified form of the wiper shown in Fig. 2.

A is a shaft of ordinary construction. The shaft A is supported in a journal-box B, formed in two parts, the lower part or pillow b having at one end-an enlargement b2, which serves as a reservoir to hold a considerable quantity of oil or other liquid lubricant, and having at its upper edges channels b4 to receive said oil, and other channels b to distribute the oil along the journal of the shaft A. The receiving channels, or oil-receivers b4, are arranged on opposite sides of the reservoir b2 (see Figs. 4., 5, 7, 9 and 12), and are connected toleach other by an equalizing passage ZJS, by which the oil remains at the same heightin both receivers. After the receivers h4 are sufticiently lled, the oil runs from them through holes b1 in gates or partitions Z212 which separate said receivers from the distributin g channels b into said receiving channels, and by the latter are conducted along the opposite sides of the journal of the shaft. The size of the holes bw regulates the flow of oil to the journal of the shaft and tends to keep said flow uniform.

From the distributing channels b the oil runs through holes b through the inner walls of said channels to the journal of the shaft A, said wall being thinned for this purpose at bis. The number of these holes may be varied to suit the requirements of circumstances. v

The babbitting or lining O of the lower half of the j ournalbox is omitted or cut away on each side at the top at c to form an accumulating space c' for the oil.

The cap b or upper half of the journal-box B is of a suitable shape to fit the lower, and is otherwise substantially of the usual form, except that said cap is provided with a hole b3 near the end farthest from the reservoir, in

which may be inserted a deflector h consisting of a sheet of leatheroid, leather or metal, arranged diagonally of said hole b3, as shown in Figs. 11 and 12, and loose enough to rest upon the shaft and to sink by its own weight in said hole as the under surface of said delector is worn away, said deiiector being set in such a manner that the upper surface of the shaft approaches the side of the deflector farthest from the adjacent end of the journal-box, so as to deflect any oil on the surface of the shaft toward the middle of said journalboxpexcept also that said cap is provided with a curved groove bi continuous with a similar groove Z718 in the lower part of the Y journal-box, there being such grooves at each end of the journal-box lled with strips of paper, leather, or similar material b9 h2o to absorb any oil on the shaft at the ends of the journal-box and to prevent the escape of oil from the journal-box.

The journal-box B has at the end farthest from the reservoir an annular groove Z711 522 which forms a drip-receiver for the usual purpose.

From the drip-receiver a returnpassage b2 leads back to the reservoir, said return-passage being slightly inclined toward said reservoir to carry back oil from the drip-receiver to said reservoir in a well-known manner. Oil is raised from the reservoir b2 either by an oil-raising roll D, shown in Figs. l, 2 and 7, or by a ring D which loosely surrounds the shaft and reaches down into the oil and is caused to rotate by friction on said shaft, both of these devices being old and not of my invention.

The oil-raising roll D is provided with a central shaft d', the journals of which rest upon C-shapcd springs d2, or a forked spring, be cause the springs d2 are preferably made in one piece, the connection between them being afoot d3, (see Figs. 1 and 2) secured by screws d4 to the bottom of the reservoir. The spring or springs cl2 hold the roll D with sufficient force against the under side of the shaft A to cause said roll to be rotated by friction on said shaft when the latteris rotated. The roll D runs between parallel guides b2, arranged at right angles to the axis of said roll in the bottom of the reservoir b2, the shaft d of said roll running in Vertical notches Z928 in said guides, said notches preventing the shaft of said roll from running off from the springs d2, and said guides preventing too great a disturbance of the oil in the reservoir and a forcing of the oil through the adjacent end of the j carnal-box. The notches Z328 are extended to the inside of the bottom of the reservoir d2, to admit the oil between said guides, and these guides are used with the ring D when said ring is substituted for the roll D.

By the use of the roll D or the ring D the oil is carried up on to the shaft and runs around the shaft in two parallel rings. From said shaft Athe oil is taken and conducted to the receivers o" by means of a forked wiper E, the points of which rest upon the top/.of the shaft, the other end of said wiper being se cured in one of the oil-receivers b4, the end of said wiper being bent at e to Iit one of said oil-receivers, as shown in Figs. 2, 9 and 13, the material of which the wiper is made be ing sheet metal of sufficient elasticity to be retained in said oil-receiver by a friction on the walls thereof, the points e of said fork when the ring D is used having a running fit on said ring. By giving to the attaching end of the ,wiper the form shown in Fig. 13, said wiper may be used with the shaft rotating in either direction,the oil from the shaft approaching the forked-end of the wiper running down ,on the inclined upper surface of the wiper and the oil from the shaft when the fork trails on the shaft running down on the inclined under side of the wiper.

By the means above described, a current of oil .is kept continually in motion throughihe journal-box and the journal of the shaftA is supported upon a film of oil. t

Dust and lint are excluded from the journal-box by the strips b 520 and by a cover Z213 arranged over the rectangular hole b3. The strips hf may be prevented from any movement caused by friction of the shaft A by'a stop or upward projection Z930 (see Fig. 12) in the bottoni of the groove b2?, which enters corresponding notches in said strips. If desired, similar stops may be used to prevent the movement of the strips h2o, but this will not ordinarily be found necessary because these 4strips cannot be carried around with the shaft without moving the strips b9.

I claim as my invention- 1. The journal-box, having a reservoir, two oil-receivers, arranged on opposite sides of said reservoir, distributing channels, openings froin said channels into the supporting surface or shaft-chambei of said journal-box and an equalizing passage connecting said oil-receivers to maintain the oil at an equal height in each of said receivers, and to apply oil equally to opposite sides of a shaft running in said journal-box, as and for the purpose specified.

2. The combination with a j ournal-box, having a reservoir, an oil-receiver, a distributing channel leading from said receiver, and opening from said channel to the supporting surface or shaft-chamber of said journal-box, of an oil-raising device, adapted to beV operated by a shaft supported in said journal-box and to raise oil to said shaft, and a wiper resting at one end directly upon said shaft and thence inclined downward and reaching into said oil-receiver to conduct oil from said shaft into said oil-receiver, as and for the purpose specified.
